Abstract
A xerographic system () includes a moving photoreceptor () and multiple toner development systems () arranged to selectively dispose regions of toner on the moving photoreceptor. A toner density sensor () is arranged to measure toner density on the moving photoreceptor over a sensor area (A). A toner coverage monitor () operatively connected with the toner density sensor () monitors toner coverage based on measurements by the toner density sensor of toner coverage calibration regions disposed on the moving photoreceptor by the multiple toner development systems. A spatial registration monitor () also operatively connected with the toner density sensor () monitors spatial registration of the multiple toner development systems based on measurements by the toner density sensor of spatial registration calibration regions disposed on the moving photoreceptor by the multiple toner development systems.
